Rezna 80 mg Tablet contains resmetirom 80 mg, a prescription medicine used for the treatment of metabolic dysfunction-associated steatohepatitis (MASH), previously known as non-alcoholic steatohepatitis (NASH), in selected adults with liver fibrosis.
Unlike general medicines or supplements marketed for fatty liver, Rezna is intended for a specific group of patients with noncirrhotic MASH and moderate to advanced liver fibrosis (F2–F3). It is used alongside appropriate diet and exercise.
What is Rezna 80 mg Used For?
Rezna 80 mg is used in adults with noncirrhotic MASH/NASH accompanied by moderate to advanced liver fibrosis.
MASH is a progressive form of fatty liver disease in which excess liver fat is accompanied by inflammation and liver-cell injury. Over time, this can contribute to fibrosis (scarring) and potentially more advanced liver disease.
Resmetirom treatment aims to address important underlying processes involved in MASH and liver fibrosis.
Why is the 80 mg Strength Important?
The 80 mg strength is a standard recommended daily dose for certain patients.
According to prescribing information for resmetirom, the recommended dosage is based on actual body weight:
- Less than 100 kg: 80 mg once daily
- 100 kg or more: 100 mg once daily
However, other factors—including interacting medicines—can affect the appropriate dose. Patients should therefore use the strength prescribed by their healthcare professional.
How Does Rezna 80 mg Work?
Resmetirom is a THR-β agonist that primarily targets thyroid hormone receptor-beta activity in the liver.
Activation of these receptors influences pathways involved in liver-fat metabolism. Resmetirom has been shown to reduce liver fat and improve important features of MASH in appropriately selected patients.
Its targeted mechanism is one reason Rezna should not be considered equivalent to general fatty-liver supplements.
How to Take Rezna 80 mg
Rezna is generally taken once daily, according to the prescribed treatment plan.
It may be taken with or without food.
Take the tablet consistently and do not increase, reduce or stop the dose without consulting the prescribing healthcare professional.
Treatment should be accompanied by the recommended diet, physical activity, weight management and management of associated metabolic conditions.
